Application filed July 16, 1917. Serial N 0. 180,711.

To all whom it may concern:

Be it known that I, PHiLo iv. Green, a citizen of the United States ofAmerica, residing at Crosse and State of Wisconsin, have inventedcertain new and useful Improvements in Tank-Gages, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

In the operation of explosive engines it is desirable to show whetherthe oil reservoir of the engine, particularly if the latter be of thesplash system of lubrication type, has-a working supply of oil,

This invention relates to a gage "for the oil systems of internalcombustion motors and to an arrangement thereof which is extremelysimple, readily arranged for any motor and extremely accurate in itsaction.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings,

Figure l is a view in section of an engine casin together with anapplied gage that embodies features of the invention;

Fig. 2 is a plan view of the dial of the gage;

Fig. 3 is a view in detail of the gage oper ating mechanism.

As herein shown, a cylindrical gage casing 1, of any suitable materialand preferably with a base flange 2, is arranged to be secured over anopening 3 in an engine casing adjacent the oil sump or reservoir. A dialplates and cover plate 5 are superposed on the inner flange 6 of a head7 formed on or secured to the casing and are clamped there by anexterior collar 8, the internal flange of which holds a glass 9 andgasket 10 down upon the dial.

A support 11, preferably in the form of a metal strip having a doubleoii'set portion at the upper end, is secured against the un derside ofthe plates so as to depend into the casing. A spindle, journaled in thechithe member ii extends through the dial plate with a suitahle in :x 23thereon traversing the dial, anti caries at its lower end a beveledpinion able stops 14-, preferably in the torn: washers, prevent theendwise movei the spindle. A segmental gear ll; prorer formed or struckout ofsheel) metal is pivoted on a pin 17 at the lower end of the member11' with its flanges and toothed La Crosse, in the county of Laupper endportion 18 in mesh with the pinion A stop 19 on the support 11 engages asegmental slot 20 in the gear and limits the oscillation of the latter.A depending and preferably bendable rod 21 secured to the lower end.portion or hub of the gear 18 carries a float 22, the bendable rodpermitting adjustment of the float so that it will 'auso the dialmechanism to properly register the level of the contents of thelubricant container in the motor in which the device is applied.

As a result of this construction, a very eiiicient, simple and readilyadjustable gage or indicator is obtained which is readily mounted inplace and calibrated to the particular motor to which it is connected.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of my invention and I do not care to limitinyseltto any particular form or arrangement of parts.

What I claim is 1. A gage comprising a casing having a dial plate, anlndex therefor. and a cover at one end, a support in the casing securedto the plate and cover, a spindle journaled in the upper portion of thesupport to operate the index, a beveled pinion on the spindle, asegmental gear pivoted to the lower portion of the support to oscillatein mesh with the pinion, a stop on the support engaging a slot in thegear and limiting the movement of the gear in either direction, and afloat connected by a rod to the gear to oscillate the latter.

2. A gage comprising a casing, a dial plate and cover plate detachablysecured over one end thereof, an index for the dial plate, a support inthe casing, a spindle journaled' in the support to operate the index, abeveled pinion on the spindle below the plate, a segmental gear pivotedto the lower portion of the support in mesh with the pinion, a stop pinon the support engaging a segmental slot in the gear to limit the motionthereof, and a float connected. by a, rod to th "our to o lists thelatter.

i casi g", a dial ei detr ichably casing, a supr from the plate, 1journnlefi in he upper portion is support to operate the index, a bevepinion secured on the lower portion of the spindle, a segmental gear, astud on the lower portion of the support and on which the gearoscillates in mesh with the pinion, a stop on the support engaging asegmental slot 1n the gear, a bendable rod secured to the hub portion ofthe gear, and a flpat on the end of the rod.

'4. A gage comprising a casing having a dial plate, an index thereforand a cover at the outer end, a support extending below the plate and inthe casing, a spindle journaled on the support to operate the index, abeveled pinion on the spindle, a segmental gear of sheet metal providedwith an upper flanged and toothed end that meshes with the pinion andwith a segmental slot between the PiYOt thereof and the teeth, a stoppin on the support engaging the slot, and a float operatively connectedto the gear to oscillate the latter.

5. A gage comprising a casing having a dial plate and cover at the headthereof, a support extending into the casing and below the plate, aspindle journaled in the upper portion of the support to operate theindex,

a beveled gear on the spindle, a segmental sheet metal gear having aflanged and toothed upper end meshing with the pinion and a hub portionrotatably secured to a stud of the support, a stop limiting themoifement of the gear,- and a bendable rod connecting a fioat to the hubportion. of the gear.

In testimony whereof I affix my signature in presence of two witnesses.
